Title: Anaerobic digestion of highly-concentrated organic waste water
Inventor: CHIGUSA KAORU
IPC: C02F3/28
Filed: 1981-09-16
Abstract: PURPOSE:To enhance the efficiency of anaerobic digesting reaction, by anaerobically digesting highly-concentrated organic waste water in a first digesting vessel, concentrating digestive fluid from the first digesting vessel with a centrifugal concentrator, and returning the concentrated liquid to the first digesting vessel. CONSTITUTION:Highly-concentrated organic waste water (a) such as night soil is anaerobically digested in a first digesting vessel 1, the resulting digestive fluid is concentrated by a centrifugal concentrator 2 without being brought into contact with oxygen in air, and at least a part of the concentrated liquid is returned to the first digesting vessel 1 while the remainder is discharged as excess sludge (e). As a result, a condition in each vessel comes to the optimum for digestion, so that the efficiency of digestion is remarkably improved. Consequently, the method can be applied for difficulty decomposable stroma-contg. waste water or highly-loaded operation, and the reduction of the total volume can make the size of installation small.

Title: Controller of video camera
Inventor: TAMURA EIJI
IPC: H04N5/232
Filed: 1984-07-13
Abstract: PURPOSE:To attain effective camera control by displaying a controlled system and a controlled variable to a camera on a picture plane to attain ease of confirmation of the controlled system and variable and limiting the number of key operations on a keyboard to the limited number of times to eliminate the error in the key operation. CONSTITUTION:The pattern of the operating panel of the camera is displayed on a display scope 22 by a personal computer 20 and the display state on the panel is changed by the computer 20. Then a serial data in response to the change is transmitted from the computer 20, fed to a microcomputer 9 via an external input terminal 7B of the video camera 1, the computer 9 decodes the serial data and controls each part of the camera. Since the controlled system and the controlled variable to the camera 1 are displayed on the screen, the confirmation of the controlled system and the controlled variable is attained easily. Even if there are plural controlled variables to the camera 1, since the key operation on the keyboard is limited to the limited number of times, the error of the key operation is eliminated.

Title: Optical type shape measuring device
Inventor: WASA YASUHIRO
IPC: B23Q17/24
Filed: 1993-06-17
Abstract: PURPOSE:To provide an optical type shape measuring device which is constituted to high-precisely measure the shape of a work on a machine tool, such as a lathe. CONSTITUTION:Under environment wherein oil and dust are serious at other time than a measurement time, such as a machining time, an object 1 to be measured is relatively moved from a space between a projecting part 2 and a light receiving part 3. A distance between the projecting part 2 and the light receiving part 3 is decreased and a projection opening part 4 is superposed with a light receiving opening part 5 and the superposed part is brought into a state to be not exposed to the outside. Thus, the projection opening part 4 and the light receiving opening part 5 are shut off from the outside and oil and dust are prevented from entering from the outside without installing a different shutter mechanism. During measurement, an air flow 6 is injected in a direction, crossing an optical axis at right angles, from an air flow generating mechanism 21. This constitution causes the change of entrance direction of oil and dust, intending to enter the projecting part 2 and the light receiving part 3 from a position above an optical axis, resulting in prevention of entrance of dust to the interior of a device.

Filed: 1990-06-06
Abstract: PURPOSE:To eliminate the influence of scattered rays even when sufficient maze structure can not be secured by providing a movable mechanism at part of the shield wall and arranging a movable shield wall which can be stored in the shield wall when opened. CONSTITUTION:The shield wall 14 is provided so as to partition the high-dosage equivalent area 12 and low-dosage equivalent area 13 of radiation handling facilities 11 where a high-radiation source equipment 7 is arranged internally, and a maze wall 16 which prevents direct rays so as to constitute an entrance/ exit door 15 is provided to the wall 14. Further, the movable shield wall 8 which cuts off scattered rays is mounted on the wall 16 movably on a rail laid on the floor surface with casters fitted to the lower end. When the wall 8 is not used, the influence of single-time scattering from the equipment 17 extends to the area 13, which is not preferable as to exposure, but the scattered light is cut off by the wall 8 to reduce radiation reaching the door 15, thereby obtaining the same shield effect with twice scattering. Therefore, even when a sufficient maze structure can not be secured, the same shield effect is obtained and rational arrangement design is enabled.

Title: Optical switch
Inventor: INOUE HIROAKI
IPC: G02F1/31
Filed: 1984-07-17
Abstract: PURPOSE:To reduce the driving voltage and the power consumption of a waveguide- type optical switch using semiconductor materials and to facilitate the production by setting the film thickness of a waveguide layer so that the variation of an equivalent refractive index is maximum for a certain applied voltage. CONSTITUTION:A three-layered thin film waveguide is formed with a GaAs semiconductor, and Schottky electrodes 3 are arranged on the front face of an n<+>-GaAs substrate 2, and an ohmic electrode 4 is arranged on its rear face. When the thickness of an n<->-GaAs optical waveguide layer 1 and the applied voltage are denoted as (h) and V respectively, an applied electric field E is equal to V/h, and a variation DELTAetaomega of a refractive index etaomega of the optical waveguide layer 1 due to the electrooptic effect is expressed with an equation I where (r) is the electrooptic constant. A variation DELTAetae of the equivalent refractive index of the propagation mode in the optical waveguide layer 1 is expressed with an equation II. When the applied voltage V is constant, the value DELTAetae takes a maximum value. If the thickness of the optical waveguide layer 1 is increased from 2mum to 3mum, the variation of the equivalent refractive index is increased by 50% in case of the same voltage. Consequently, the thickness of the optical waveguide 1 is so set that the value DELTAetae is maximum, thereby reducing the driving voltage.

Title: Hydraulic controller for automatic transmission
Inventor: HAYAZAKI YASUICHI
IPC: F16H59/18
Filed: 1987-06-15
Abstract: PURPOSE:To obtain a proper shift interval in a low throttle opening area by enabling setting of an up-shift point to the high speed side only in a small throttle opening area. CONSTITUTION:When the pressure in response to the opening of a throttle works in a third port 70 is lower than a fixed pressure in response to the force of a spring 64, a throttle readjustment valve 10 regulates the fixed pressure in response to the force of the spring 64, and the pressure is output from a second port 68 to a shift valve. Further, when the pressure in response to the throttle opening becomes higher than the fixed value, the pressure is output as it is from the second port 68. A fixed pressure always acts on the shift valve in an area where the opening of throttle is small accordingly, and it is against the pressure in response to a vehicle speed, and therefore the shift line in the small throttle opening area is set on the high speed side. It is thus possible to prevent two shift lines to close too much in the small throttle opening area.
